dear rawzi, your son is a very very smart boy no doubt. we are learning even more through his own experiments. i wonder, if he likes the taste of those lobsters for real. god bless him. 
He said it was easier to swallow than the other fish. As far as taste, he said it was very weird. He says the taste was unusual and intense. He was still somehow getting the taste or the lobster somehow in the back of his mouth till yesterday.
people who eat strictly raw food without any starches, get the fast result. 
He says he will listen to you now about starch. The yucca he ate a few days ago looks likely to be what triggered some problems now.
It appears his stool was black because of blood. He only poops every other day, so we don't know if the next poop is black. He thinks because it was a big clam, and he swallowed it whole down his small sensitive throat, that bits of shell were in the clam, and the bits of shell scratched his intestines. He's still worried about the stool. He says he may want a doctor to see him in a few hours. He is feeling better now, as far as energy, and thinks maybe the bleeding somehow had made him so incredibly exhausted, dopey and muscular fatigue and tightness. He hopes the blood thing is over. It looks like it may have been a lot of blood.
edit: He also ate passion fruit during that time. He still thinks it's the clam though. The reason we're mentioning the passion fruit is because he doesn't normally eat it, and the seeds were hard for him to chew. So maybe the seeds scratched, but they would have had to do it more quickly as for timing.
